Carry out daily maintenance for gas generator in strict accordance with the requirements to ensure reliable operation of the unit. Good maintenance can ensure the reliable operation of the unit. Under normal use, the maintenance should be carried out according to the requirements of daily maintenance, weekly maintenance and monthly maintenance.

通過這些規定的保養,能及時發現機組是否存在聲音異常、動作異常、外觀異常、溫度異常、壓力異常和氣味異常等故障現象,從而及時對機組進行檢查和調整,進而有針對性的加以解決,確保瓦斯發電機運行在好狀態。在這些保養要求中,要特別注意以下三個方面的檢查和保養:

Through the maintenance of these regulations, we can timely find out whether there are abnormal sound, abnormal action, abnormal appearance, abnormal temperature, abnormal pressure, abnormal smell and other fault phenomena in the unit, so as to timely check and adjust the unit, and then solve them pertinently, so as to ensure that the gas generator runs in a good state. In these maintenance requirements, special attention should be paid to the following three aspects of inspection and maintenance:

(1)潤滑系統的檢查和保養。該種類型機組由于存在運轉部件多,運轉部件工作條件惡劣,大多處在高溫、高沖擊載荷狀態下,需要潤滑的部位較多,對潤滑系統的可靠性要求較為苛刻,因此要注意檢查潤滑油系統的油質情況、油位情況、油溫和油壓情況,注意離心濾清器和機油濾清器的清洗,避免出現因潤滑不好造成的機組零部件磨損加劇,縮短機組零部件的使用壽命,加大維護工作量。

(1) Inspection and maintenance of lubrication system. This type of unit has many operating components, and the operating conditions of the operating components are harsh. Most of the operating components are under high temperature and high impact load. There are many parts that need to be lubricated, and the reliability of the lubrication system is more demanding. Therefore, it is necessary to pay attention to check the oil quality, oil level, oil temperature and oil pressure of the lubricating oil system, and pay attention to the cleaning of centrifugal filter and oil filter, To avoid the aggravation of the wear of the unit parts caused by poor lubrication, shorten the service life of the unit parts and increase the maintenance workload.

(2)空氣過濾器的檢查和保養。空氣過濾器如果運轉良好的話,將有用地避免因進氣阻力大引起的增壓壓力下降過大,進而造成渦輪增壓器出現漏油現象；還可避免因流量減少引起的渦輪增壓器壓氣機喘振現象。因此要定期清理空氣過濾器,必要時更換新濾芯。

(2) Inspection and maintenance of air filter. If the air filter works well, it will effectively avoid the excessive pressure drop caused by the large intake resistance, which will cause the oil leakage of the turbocharger; It can also avoid the surge phenomenon of turbocharger compressor caused by flow reduction. Therefore, clean the air filter regularly and replace the filter element if necessary.

(3)相關間隙和角度的檢查和調整。主要是火花塞間隙、氣門間隙和配氣定時等的檢查和調整。機組運行一段時間后,火花塞的間隙會有所變大,這是正常現象。

(3) Check and adjust the clearance and angle. It mainly includes the inspection and adjustment of spark plug clearance, valve clearance and valve timing. After the unit has been running for a period of time, the gap of spark plug will become larger, which is a normal phenomenon.

瓦斯發電機經長時間運轉后,由于配氣機構的磨損和松動等原因,會引起氣門間隙的變化,應定期檢查并調整氣門間隙。配氣定時在正常情況下不需要進行調整,當機組各缸工作狀態出現異常時,應首先檢查指針上止點指示位置是否正確,檢查傳動系統各齒輪傳動記號是否對準,整個系統的裝配關系及氣門間隙是否正確。若經檢查調整后,仍與規定值差異較大時,則應考慮凸輪軸或齒輪傳動件有無損壞現象,必要時進行修復或更換。

Gas generator after a long time of operation, due to the valve train wear and loose and other reasons, will cause changes in valve clearance, should be regularly checked and adjusted valve clearance. It is not necessary to adjust the valve timing under normal conditions. When the working state of each cylinder of the unit is abnormal, it is necessary to first check whether the indication position of the top dead center of the pointer is correct, whether the gear transmission marks of the transmission system are aligned, and whether the assembly relationship and valve clearance of the whole system are correct. If there is still a big difference between the value and the specified value after inspection and adjustment, the camshaft or gear transmission parts shall be considered for damage and repaired or replaced if necessary.
